Intravascular papillary endothelial hyperplasia or Masson's tumor is a rare benign vascular pathology. It mainly affects lower limbs and is not related to the gender or age of the patients. Evaluation by clinical history and imaging exams can be confused with other soft tissue tumors. The purpose of this article is to describe a case attended at a university hospital in Porto Alegre, Brazil. In the present study, the authors report a case of a 54-year-old male patient with the presence of nodulation on the back of the right foot. After inconclusive biopsy, the treatment of choice was surgical resection of the tumor with free margins. Anatomopathological study of the surgical specimen was compatible with Masson's tumor. A 6-month follow-up did not show any recurrence of the lesion. With this case, the authors wish to highlight this pathology among the differential diagnoses for soft tissue tumors.
